What is an intervention group?

An intervention group is a subset of participants in a study or experiment who receive a specific treatment, program, or intervention designed to bring about a change or improvement in a particular outcome. This group is typically compared to a control group, which does not receive the intervention, to assess the effectiveness of the treatment. The goal is to determine whether the intervention produces a significant effect relative to the control conditions. Intervention groups are commonly used in clinical trials, social science research, and educational studies.
